One of the main factors which influence the effectiveness of the learning process is the interaction that exists between the teacher and the student. The current research indicates that different interactions have different effects. There are two methods used for implementing distance learning systems, i.e. synchronous and asynchronous. The present study refers to the cognitive interaction and differentiates between surface processes and deep processes. The interaction level between the students and the teacher and among the students was found to be a significant factor in determining the effectiveness of the teaching method.
